5 among the objects of my invention are to' provide an improved sashconstruction and particularly for the meeting rails whereby a moreeffective weather seal is formed and whereby the window panes areeffectively .0 and more conveniently held in position and whereby alocking mechanism for the window sashes may be mounted upon andcooperate with the meeting rails to hold the sashes locked and toprovide such further L5 objects, advantages, and capabilities as willlater more fully appear and are inherently possessed bythe invention.

My invention further resides in the combi nation, construction andarrangement of parts illustrated in the accompanying drawmgs and, whileIhave shown therein a preferred embodiment of my invention, I desire thesame to be understood as illustrative only and not as limiting thisinvention.

In the drawings annexed-hereto and forming a part hereof Fig. 1 is abroken elevation of a window embodying my present improvements; Fig. 2'is a broken horizontal section substantially along the plane indicatedby the line 22 Fig. 1; Fig. 3 is an enlarged view of the lock shown 1nFig. 1; Fig. 4 is a broken vertical section substantially along theplane indicated by the line 4-4 Fig. 1;

Referring more in detail to the annexed drawings, numeral 1 denotes ingeneral the window casing or frame and numerals 2 and 3 the lower and'upper sashes, respectively. The frame comprises -a pair of side memibent outwardly to provide a projection under bers 4, a head member 5 anda sill 6, thewhich a flange 11 of a removable plate 12 may be inserted.The opposite edge of this plate 12 is folded over so that it may beinserted in a groove formed by similarly.

folding an edge of the pulley stile 7. This forms a tight connection atthis point but still leaves it possible to separate the cap plate 12 bythe removal of screws 14 which may be of any desired number, two beinshown in the drawings. Upon removal 0 the plate 12 it will be possibleto have access to the weights 15 so that they may be easily removed orput in place when desired. A plate 16 is hinged'to oneinterior' wall ofside member 4 and may be held in proper position by means of springs orotherwise, as desired. After the plate 12 has been removed and the firstweight 15 taken out of the opening in the casing, it will be possible toswing the plate 16 out of the way so that the other weight 15 may bebrought out through the the removal of plate 12. will be understood thatthe weights 15 may be cylindrical, as shown, or rectangular in crosssection or may have other desired shapes. Whatever shape is selected,the hinged plate 16 serves as a separator to keep the weights frominterfering by striking each other.

Near their upper portions, the pulley stiles 7 have portions punched outas-indicated at 17 to form the hooks 18 by means of which the pulleycasings 19 are held in place. Pulleys 20 are carried by shafts 21 withinthese casings and over the pulleys pass sash cords 22 which are attachedat one. end to the sashes and at the opposite end to sash weights 15. Inapplying the pulley casings 19'to the frame, the hooks 18 are punchedout at right angles to the pulley stiles 7 and then passed throughopenings in flanges of the casings 19. After the casings are in placethe hooks 18 are bent up and down, respectively, to hold the casings inplace.

As shown in Fig. 2, the .pulley stiles 7 arev folded during the formingprocess to form two pairs ofgrooves as'indicated at 24. 'In this figurethe numeral denotes (by dotted lines) the positions of the pulo eningmade by- It leys 20 and their casings 19. It will thus be seen that eachof these casings fits in between a pair of grooves 24 and that the cords22 coming'down from the pulleys 20 will be in position to be attached tothe sashes. In'the case of the lower sash, any suitable means 26 is usedto fasten the rope 22 to the top of the sash, while, in the case of theupper sash, the rope passes through an openin in the'top edge thereofand down to a suita le securing means, such as a pin 27 which should befar enough below the .level ofthe axle or shaft '21 not to interferewith the pulley when the sash is raised to its uppermost limit. It willhe understood -from this that there should be an opening in the uppercorner of the sash of sufficient size to pass the pulley as the sash israised.

If desired, the parts may be welded together at 9 or reliance may beplaced entirely upon a close fit'to prevent moisture and wind frompassing through this joint.

It is preferable, however, that side mem 'bers 4, head member 5 and sill6 should be thus be seen that the construction of all the outerrails. ofthe sashes is the same.

While the meeting rails 32 and 33 are not absolutely identical, asshown, they are substantially so and could, if desired, be madeidentical. Each of the rails is provided with an abutment 34 formed byappropriate "and an u per stop 41. buildingii bending of the sheet metalfrom which the rails are made. Each rail is formed with a groove orpocket 35, formed bybending the metal appropriately, for the receptionof one edge 36 of the glass stop 37, a part 38 of which rests againstthe glass to hold it tightly in place. It will be seen by reference toFig. 4 that parts 36 and 38 are offset slightly relatively to eachother, the purwe of this being pointed out later. Re-

erring more particularly to the lower part of Fig. 1, it will be seenthat there is'a lower glass .stop 39,- two lateral stops. 40 Assumingthat the as been erected and, during the process of erection, the frameand sashes have been put in position, it will be seen that the sashe'sare ready to receive the glass After thishas been put in position thelower} stop 39 is inserted into position by having its portion 36inserted in the groove 35. Side stops 40 are then put inplace in thesame manner, thereby locking stop 39 in place. Stop 41 hasits portion 38so cut that it will fit in between the stops 40 and it can, therefore,be shoved upwardly into place, portion 36 goinginto the groove 35.

The part 36 of the upper stop 41 as well as the meeting rail 33, isprovided with holes for the reception of screws 43 whereby stop 41 isheld in place. Since the parts 36 and 38 are not in the same plane, itis possible for part 36 of stop 41 to rest on part 38 of stops 40 whilebeing put into place, but this would be very troublesome if the twoparts were not offset laterally from each other. The construction .ofthe upper sash is similar to that of the lower sash.

It will be understood that the glass in both of these sashes maybe'unitary as-we-ll as made in'a plurality of pieces, as shown in thedrawings. When a plurality of lights of glass are used, muntins ormullions 44 are used to cover the junction between the glasses, as shownin Fig. 2. These mullions comprise outer and inner plates which aresecured together by means of a plurality of T bolts 45, )rovided with.suitable nuts, as

shown in ig. 2. Ill-setting the glass, use

is made of asuitable sealing material 46, q

for example, putty. This prevents wind and water from passing in betweenthe glass and its mounting, as well as aiding in preventing rattling ofthe glass.

The sill 6 is provided with a ridge 47 in the plane of the lower sash,as shown in Fig.

3, so that the two sides of the lower rail 31 may come down and engagetightly on opposite sides of this ridge to form a tight joint therewith.The lower rail is provided with one or more handles 48 secured therer toin any desiredmanner. By means of these the sash can be r ised andlowered quite readily. i

The meeting sash rails 32 and 33 are provided with a locking devicecomprising a member 49 suitably secured as by welding I in the extension50 of rail 32 and extending upwardly through an aperture provided in theupper wall of this extension. The protruding portion of the member 49 isof such a length as to extend through an aperture 1 provided in theextension 51 of the rail 33 and to extend above the latter, the partthus so extending being .provided with an aperture or slot 49. On therail 33 is secured a plate 52 by means of screws or bolts 52 and 52 Thisplate carries a pivot 53 to which is pivoted a latch or hook member 54having a locking tongue 54" adapted to be swung into a slot or aperture49 and a finger piece 54". The member 54 may be swung to one side'torelieve the tongue 54" from the slot 49 in member 49 for unlocking, andto the position shown in Fig. 2 for locking when the tongue 54 extendsthrough the slot 49*. i
